H V a ueatibi filed Ha es, This invention-relates to a machine forheading and flanglng metal barrels, and more particularly to a machinefor rolling the beads and flanges into sheet metal beware;

n stiffening the shell and preparing it or the reception ofbarrel'heads.

shells for the purpose of roundin The principal-object of this inventionis to provide a simple, durable, and eflicient machine which receives,automatically, beads and flanges, and discharges the barrel ,blanks in acontinuous stream, thereby materially.

reducing the cost of this operation and the number of men required tobead and flange a quantity of barrels. y

' A further object is to provide such a machine which will bead andflange barrel blanks having substantial" variations in length, or whichare not square attheir ends or whichv are badly out of round, thebarrel. blanks, when discharged from the present-- machine, being ofround form, properly provided" beaded intermediate the ends and withproperly spaced end flanges.

* Another object isto provide such a machine in which the barrels areadvanced with'a stepby-step movement and in which the means for holdingthe barrels are moved out of the path of. the barrel shells during theperiod in which the advancing mechanism is in operation and in which-thebarrel holding means are locked in their operative position during theforming operation on the barrel.

Another aim-is to so'mount and actuate; the forming rolls carried bythemovable-barrel holding mechanism that upon completion of the inwardmovement of the holdin means, the rolls are moved against the barr Ashell to form the same. 40

A. still further aim is to provide cam means for reliably maintainingthe'synchronism Of T operations of the machine. a

. Still further purposes are to provide a durabl e machine whichwillstand up under the continuous services it is designed to give, whichis com aratlvely simple considering the function w ich it performs,which is readily adjustable to difierent sizes of barrels and I whichoperates to flange and bead the barrels 5 uniformly.

The barrel shell 20 produced by the machine comprises a cyhndrical sheetmetal open ended body having its opposite ends turned out to provideflanges .21 at its opposite ends, and having a plurality of annularbeads 22 rolled out from the sheet metal body to strengthen the barrel.The barrel shell s received as a plain cylindrical body and 1ssuccessively acted on by cooperating rolls at difierent stations to headand flange the barrel.

In the machine shown, the barrel shell is first beaded and then flanged,but it is ob- VlOllS that these operations can be reversed.

It is also obvious that the invention can be practiced in connectionwith any cylindrical tbody to be provided with annular deformaions.

comprises a horizontal conveyer on which the barrels are placed withtheir axes parallel, a Geneva gear for advancing the barrels tosuccessive slmi'lar positions two horizontally movable carriagesarranged on opposite sides 'of the conveyer and having heads adapted toengage the ends of the barrels to center them relative to the formingrolls, a cam opermoving the carriages together each time the conveyercomes to rest, beading rolls mounted on ea'ch carriage and movableairiallg; therewith toenter the opposite ends of the barrel at one ofits stations, a second pair of beading rolls mounted under the conveyerand movable transverselyinto operative relation w th said first beadinrolls, cam means for moving said last named ading rolls into operativerelation with the first named beading rolls after the conveyer hasstopped and sai heads have been moved inwardly to center the barrels,and a set of flanging rolls 1 mounted and actuated inthe same manner assaid beadingfrolls to flange the barrels at another station.

Tlw barrel conveying qriecham'em the opposite ends of this frame 24 aretwo pairs of spaced arms 25 which are bolted to the frame 23, as shownin Fig 2. Each of these arms 25 is formed to provide upwardly extendingsupports 26 whichcarry cross bars 27 at their upper ends. These crossbars 27 can be of any 'suitable form and support two spaced longitudinalchannel bars which form tracks 28 for the upper stretch ofthecenveyerchain 29 and also support the barrels 20' as they are movedalong by the upper stretch of the conveyer chain and insure theirvertical alinement relative to the forming devices.

The front ends of the conveyer chains 29 pass around a pair of spacedchanneled wheels 30 which are secured to a shaft 31 journaled at itsends in the ends of the front supporting arms 25, and the rear ends ofthese con-.

veyer driving wheels 32 are mounted on a conveyer drive shaftB i whichis. journaled at its opposite ends in the outer ends of the rearwardlyextending supporting arms 25.

, To move the barrels along the tracks 28 in spaced relation to oneanother, driving arms or wings 35 are provided which receive In itsgeneral organizatlon this invention the. barrels between them and compelthe barrels to be intermittently advanced along the tracks 28 inresponse to the movement of the conveyer chains as hereinafterdescribed. These driving arms are arranged st) that the driving arms ofone chain are arranged opposite the driving arms of the other chain andeach driving arm comprises an outwardly extending arm 36 which is'suitably secured at its inner 'end to a link of the conveyer chain 29and at its outer end carries a cross arm 31. The ends of the cross armsare preferably inclined so that when they are traversing the upperstretch of the conveyer chain, they form an inclined support for theopposite sides ofthe barrel shell carried therebetween. r

y In operation, the operator places each barrel shell 20 on the'frontend ofthe conveyer chains 29 in advance of the rising conveymgarms 35.These arms move the barrel upwardly onto the tracks 28 along which it isconveyed to the rear end of the machine. As the conveyer arms .35, passdownwardly around the rear driving wheels 32, the finished barrel shellsare released and roll from the machine. A

An intermittent or step-by-step movement isimp'arted to the conveyerchain by a Geneva gear 38, this gear being so designed that thestep-by-step movement of the conveyer-chains brings the barrels .carried.thereby to sac- 'cessive stations. By means the forming devices forsuccessively operating on the barrels can be arranged along the path ofthe barrels at their stations when the conveyer.

chain is not moving and'by' operating these forming devices during theperiod of nonmovement of the c'onveyer, each barrel will be operated onby the formmgdevices.

. This Geneva gear 38- includes the usual star wheel 39 which is mountedon the conveyer drive shaft 34 and has the usual indented .faces' 40 andradial slots 41. The star wheel- 39 is turned from the main drive shaft42 by a slotted driving arm 43. ,This driving "'ary by the engagement.of its indented faces 40 with the periphery of a wheel'50 fixed on themain drive shaft 42. This wheel 'is provided with the usual recess 51which re- 1 ceivesthe points ofthe star wheel 39 and v 7 permits thestar wheel to be turned ,by thedriving arm 43, The star'wheel39 has fourradial slots 41 and consequently it is turned once for every four:revolutions of the drive shaft 42 and its associate wheel 50, the marwheel 39 being held stationaryduring the;

greater part of the revolution of the drive shaft. is advancedstep-by-step to move the barrel shells 20 from station to station andduring thegreater period the barrel shells are at rest and beingoperated on by theforming de- .the frame or bed of the machine-is,formed.

The barrel gayz'ng and centering mechanism In order to center eachbarrel'shell prop erly relative to the conveyer mechanism and in properrelation to the forming rolls which act upon opposite ends of the shell,gaging and "centering devices are provided w ich are preferablyconstructed as follows:

I The preliminary gagingi and centering of the barrelshells 20 iseffected by two stationary gage plates'60? These gage .fplates rise fromthe crossbars 27 and are arranged on opposite sides'of the conveyerchains 29 so that in order to passbetween these gage pl tes,.the .barrelmust be placed on the conveg er in centered relation thereto. On oneside of the center ofthe conveyer,

. to provide, a fixed pedestal 63, and, as best shown in Fig. 9, on theopposite side of the conveyer, the frame or bed 23 carries a pair oftransverse horizontal .tracks or rails 64 which support a movablepedestal 65. This movable pedestal is; ad'ustably movable on its rails64 toward and rom the conveyer by means of a screw 66which, as showninFig.

of the bed 23.

By this means, the conveyer chain- 9, turns in a nut 67 formed on theunder 1 side of the movable pedestal and is turned by a crank 68 whichis arranged at one side Both'the fixed pedestal 63 and the movablepedestal fifiare formed toprovide a pair of horizontal transverse tracks69 on which the shoes 70 of a pair-0f transversely movable carriages 71and 72 rest, onecarriage being" ararnged at each side of the conveyer.

To hold these sho'es70 in engagement withthe tracks 67, rails 73 arebolted to the pedestals and overhang the shoes 70 as best shown in Iig.1.

Each of thesecarriages 71 and 72 comprisesside walls 74,"a lowerhorizontal wall 75, intermediate vertical walls 76 spaced walls'74, anouter'end wall 77 and an inner end wall 78., The upper part of each car;riage is covered by a cover plate 79 which is from and extendingparallel with the side i bolted to 'the jends, side and intermediatewallsof the carriage inany suitable manner.

Vertical, gaging and centering platlas '80 are secured to bpposing sidesof the carriages 71 and 72 and are adapted to engage the ends of thebarrel shells on the conveyer when the carriages are moved together forthe purpose of centering the same relative to the forming devices. Eachcarriage carries two of these gaging plates 80, one being adapted tocooperate in centering the barrel during the beading operationat thebeading station and the other cooperating with the barrel duringtheflanging operation at the flanging station. Each ofthese I gaging,plates is secured to a plurality'of outwardly extending supportinghorizontal rods 81, these rods being slldingly receivedln bosses 82 onthe carriage so that the plates are adjustable toward and from eachother i .to permit ofithe gaging and centering of bara I rels ofdiderent heights. The plates are held in thelr adjusted position by setscrews 8'31which are arranged in the bosses 82 and engage the sides ofthe supporting rods 81.

The means for reciprocating the two carriages 71 and 7 2 toward and fromeach-other while the'conveyer mechanism is at rest is preferablyconstructed as follows:

Asshown in Fig. 3 a cam'85 is mounted on themain drive shaft 42,this'cam having a cam groove 86 which is disposed so that I its salientand receding portions face in the direction. of the length of the driveshaft 42. In this cam groove 86 is arranged a roller '87 which'ismounted on the upper end of a rock arm 88. This rock arm, as shown' inFig.13, is fixed to a rock shaft 89 suitably journaled' in the mainframe, and at its other .end, this rock shaft carries a second rock arm90. The rock arm 90 is connected by a link 91 with a rock-lever92, whichis pivotally mounted at its lower end on the machine frame 23. As bestshown in Fig. 9, this rock lever 92 swings transversely of the machine,and is substantially longer than the rock arm 90 which actuates it.

As best shown in Fig. 5, the rock lever 92 is relatively wide and at itsupper end carries two swinging members 93 which are mounted on pivotpins 94. One of these swinging members 93 carries a rod 95 which extendsin the direction of the carriage 71 and the other swinging membercarries a similar rod v96 which extends in the direction of the oppositecarriage 72. Each of these rods is threaded at its inner end and issecured to the respective swinging member 93 by means of two nuts 97which, as bestshown in Fig. 9, permit of increasing or decreasing theeffective length of the rods to vary the movement of the carriages.

At its outer end, the rod 95 is pivotally secured to an ear 98projecting downwardly from the lower wall of the carriage 71, and theouter end of the other threaded rod 96 is connected to the lower end ofa vertical rock beam 99, as best shown in Fig. 13. This beam is pivotedat its center to the machine frame for transverse swinging movement andat its upper end is connected by a link 991 with the front wall of thecarriage 72.

It is apparent that each time that the main drive-shaft 42 is turned,the cam 85 is rotated and the roller 87 .is caused totraverse its camgroove 86. This cam groove imparts a transverse reciprocatory movementto the rock arm 88 which carries the roller 87 and also to the rockarm90 and rock lever 92 which are operatively connected with the rockarm 88. As the rock lever 92 is moved in the direction of the carriage71, the rod 95 carried thereby operates to move this carriage outwardlyor away from the conveyer and thebar'rel shells on the conveyer. At thesame time, the threaded rod 96 connected to the rock lever 92 is movedinwardly and this movement-of the threaded rod 96 moves the lower end ofthe rock beam 99 inwardly. This movement of the rock beam 99- causes itsouter end to swing outwardly and since the outer end of the rock beam99- is connected to the carriage 7 2 by the link 991 this carriageis'also' moved outwardly. It therefore folf lowthat eachttime the maindrive shaft 42 1s turned, the two carriages -are moved toward and fromeach other to center the bar rels on the conveyer relative to theforming devices. with relation to the conveyer that the inward movementof the carriages 71 and 7 2 follows the advance movement of the con'veyer and. the outward movement of these The cam 85 is so formed andtimed' The forming mechanism 7 In the machine shown in the drawings, the

- barrel shells are provided with the beads 22 at station A while theconveyer is at rest and while the barrel is centered by the first pairof movable gage plates 80 and is provided with the outturned flanges 21at its opposite ends at station B, while the conveyer is again at restand the barrel centered between the second pair of movable gage plates80. It is obvious, however, that this sequence of operations can bereversed and hence this sequence is used for the purpose of illustrationonly.

Each carriage 71 and- 72 carries an upper beading roll 100, these rollsopposing each other and being arranged to enter the opposite ends of thebarrel shell while the same is at rest at station A. As best shown inFigs. 6 and 7 each beading roll 100 is keyed on the end of a shaft 101which shaft is journaled in a vertically adjustable bearing block 102and is continuously rotated by a pinion 103 fixed to the outer end ofthe shaft 101. As

best shown in Fig. 11, the bearing block 102. i

which carries the beading roll shaft 101 is guided in vertical waysprovided in the outer and intermediate walls 7 1 and 76 at the front endof the carriage and the vertical adjustment of each bearing block iseffected by a pair of screws 104 which extend through the cover plate 79 and supporteach bearing block.

(lo-operating with each of these upper beading rolls is a verticallymovable lower beading roll 106 which is also power driven and is movedupwardly against the under side of the rotating beading roll 100 ashereinaft-er described after the beading rolls 100 have entered the endsof the barrel and thereby corru'gate or bead the opposite ends of theshell. For this purpose, each upper beading roll 100 is provided withannular beads or 'corrugations 107 which cooperate with correspondinchannels in each lower roll 106 so. that t e outwardly projecting beads22 are provided at opposite ends of the barrel as best shown in Fig. 15.

- Ina similar manner each carriage carries an upper power drivenflanging roll 108, the upper flanging rolls 108 of the two carriagesbeing arranged axially in line and being arranged to enter the oppositeends of the barrelshell 20 while it is at rest at station B and held ina centered position by the second set of movable guide plates 80. In thesame manner as the upper beadingrolls 100,'each upper flanging roll108is keyed on the outer end of an upper flangingroll shaft'109, whi hshaft is journaled in a vertically adjustab le bearing block 110 and iscontinuously rotated by a pinion 111 fixed to the outer end of the vshaft 109 is guided in vertical ways provided in the outer andintermediate walls 74 and 7 6 at the rear endof the carriage and thevertiis alsdpower driven and moved upwardly against the under side ofthe rotating upper fianging roll 108 after the flanging rolls 108' haveentered the ends of the barrel and thereby flange the opposite ends ofthe b'arrel out;

wardly.- For this purpose,.as best shown in 'Fig. 10, each upperflane'ing roll 168 is provided at its. inner end with an annularshoulder 114, and the corresponding lower roll is tapered and is adaptedtobe moved against the body of the upper Hanging roll and in closeproximitv to the shoulder 114 so that the flange 21 is formed'between"the opposing faces of the lower flanging-r'oll and the shoulder 114. Byreason ofthfe continuous rota-. tion of both flangingiolls; the. barrelis i turned so that theflange; 21 is formed on all sides.

; After the carriages 71 and 72 have been movedtogether bv the cam 85,and the upper tion to the upper rolls so that thebarrels are I beadingrolls 1001 and hanging -rolls 108 have entered the barrels, the lowerbeading rolls 106 and thellowbr Hanging rolls 113 are moved upwardlvinto cooperating relabeaded and flanged and -';"af terf.this operationare retracted prior to the retraction of the and 72; p for riving thelower carriages. Both the lower heading and flanging rolls are raised atthe same time so that r the barrel at station B is being flanged. Thiswhile the barrel at station A is being beaded,

mechanism is preferably cbnstructed as fol- I lows:,

A cam 115 is mounted on'themain drive shaft and is'composed of'two parts116 and 1 17, these twoparts being. similarly shapedandoffset-.circumferentially'relative to one another. Under this cam 115is mounted a.

" swinging cradle 118 which issupported by V a pair of swinging links119 so that the cradle is capable [of reciprocating lon 'tudinally ofthe machine as best shown in Fi 11=13. At its front end' this cradle carroller this means the cradle is positively recipro-- cured a link 123.The other end of this link l is connected with a rock arm 124 fixed to atransverse rock shaft 125. This rock shaft 125, as shown in Fi 9 isjournaled in the machine bed 23 an extends substantially across theentire width of the bed, and is arranged below each of the bearingblocks 110 supporting the lower vertically movable flanging rolls shaft126 on which the lower vertically movable flanging rolls 113 are fixed.

This lower vertically movable flangi'ng rolls shaft 126 extends thewid hof the machine and is supported at its ends in vertically movable bearmgblocks 127 carrying bearings 128 in which the lower flanging rolls shaft126 turns. Thesebearing blocks supporting the lower flanging rolls shaftmay be of any suitable construction and are guided in their vertical'movement by vertical Ways 129 formed ,on the fixed and movablepedestals 63 and which support the carriages 71 and 72, as shown in Fig.11. ()n the under side of each of these vertically movable lowerllanging rolls bearing blocks 127 a pair of ears andilowered so as tomove the lower flanging' arolls shaft 126 and the lower flanging'rollscarriedthereby into and out of o erative relation with the upper inwar ymovable flanging rolls 108 carried b the carriages 71 flangin rolls 113is derived from a pinion 132 which is keyed to one end of the lower flanrolls shaft 126and is power driven as hereinafter described.

In a similar manner the lower badin rolls 106 are moved vertically intoand out o lo 'ative relation to the u' pen-{inwardly Per ad thebarrel Imovable beading rolls 100 to v shell when it is at rest at statiorr A.

For this purpose the; (lower vertlcally -movable beading rolls 100 arefixed to a lower beading rolls shaft 133, which,

as best shown in Fig.6, extends the full width of the machin'eQ-beds"This lower beading-{rolls shaft 'is' journaled in four bearings 134which are jmo'unted in a pair of ve l; lally movable bearing blocks 135,one of th' bearing blocks 135, being arranged at eac dc of the machine.These bearing blocks 135 are guided for vertical movement in ways 136provided at the front end of the fixedjand movablepedestals 63 and 65and each is provided on its under side with, a pair of ears 137 to whichare pivotally connected links 138. These links are pivotally con nectedat their lower ends to rock arms 139 which are mounted on a transverserock shaft 140. -At one end this rock shaft has another rock arm 141secured thereto, and, as best shown in'Fig. 11, this rock arm 141 isconnected by a link 142 to the rock arm 124 on the rock shaft 125 whichraises and lowers the lower flanging rolls. 1

It is therefore apparent that when the rock shaft 125 is rocked inresponse to the rotation of the cam 115 to raise and lower the lowerflanging rolls 113 into and out of operative relation to the upperflanging rolls 108, the lower beading rolls 106 will likewise be movedinto and out of operative relation with the upper inwardly movingbeading rolls 100 through the rock arm 124 on the rock shaft 125, link142,- rock arm 141, rock shaft 140,

rock arms 139 on the rock shaft 140 the links 138 which connect the rockarms 139 with the bearing blocks 135 supporting the lower beading rollsshaft 133. By this means both the lower vertically movable beading rolls106 and the lower vertically movable flangi'ng rolls 113 aresimultaneously moved up into operative relation with the correspondingupper rolls, this movement occurring after the carriages 71 and 72 havemoved inwardly and carried the upper rolls to their operative positions,and the conveyer has brought the barrel shells to stations A and B inproper position to be beaded and flanged, respectively.

In order to insure the barrel blanks being properly positioned atstations A and B while they are beingbeaded and flanged and also toround the same if they are badly out of round, adjustable retainingrollers are provided which engage the inside and outside of eachbarrelat each station and are preferably constructed as follows: 1

Each of the vertical plates 80 which center the barrel shells on theconveyer preparatory to their being formed with beads and flan escarries a pair of adjustable rollers 144 which project inwardly towardthe conveyer and are mounted in' any suitable manner so as to beadjustable 'toward and from the upper forming rolls carried by thecarriages 71 and 72. As best shown in Fig. 5, when the barrel shells aremoved to the stations A and B by the conveyer, and the carriages 71 and72 move inwardly, the supporting rollers 144 carried by the centeringplates 80 enter the barrel shell and are arranged along the inner wallof the shell so as to hold the barrel in proper position while it isbeing formed by the forming rolls and also serve to round up the barrelswhile they are being turned. By mounting each of the rollers 144 so thateach is adjustably movable toward and from the forming roll with whichit is associated, the rollers 144 can be adapted to be used inconnection with barrels of varying diameters.

The barrel shell while being formed at each station A and B is alsosupported exteriorly by supporting and guiding rollers 145. As bestshown in Figs. 4 and 5, a pair of these rollers 145 is provided for eachpair of forming rolls, each pair of rollers being arranged at oppositesides of the lower forming roll with which it is associated, and eachroller being mounted at the upper end of an adj ustable swinging arm146.Each of these swinging arms 146 is pivotally secured at its lower end toa part of the vertically movable hearing blocks 127, 135 which carry thelower vertically movable forming rolls shafts 126, 133, so that when thelower forming rolls are moved upwardly to their operative positions, therollers 145 are likewise moved up to engage the outside of the barrelshell as shown in Fig. 5,-and thereby hold the barrel shells against theinside rollers 144 and positively hold the barrel shell in properposition for the forming operation and round up the barrel shells. Eachof the arms 146 is secured intermediate its ends to its support by aslot and bolt connection indicated at 147 so that the arms 146 can beadjustably moved toward and from the forming rolls and hence adapt thepositioning rollers carried thereby to barrel shells of differentdiameters.

It is apparent that while the barrel shells are being operated on by thebeading and flanging rolls, the carriages 71 and 72 which carry theupper flanging rolls must be held against outward movement since if theymove outwardly, or have any movement, the upper forming rolls move outof position and operate imperfectly in beading or flanging the barrel.Special means for locking the carriages in their inner or operativeposition are therefore provided, which, when the car riages 71 and 72and forming rolls have been moved to their operative positions,positively lock the carriages 71 and 72 in this position. These meansare preferably constructed as follows 2 Formed on the upper side of eachof the vertically moving bearing blocks 127 and 135 which respectivelycarry the lower flanging rolls shaft 126 and the lower beading rollsshaft 133 and are moved upwardly each time the carriages 71 and 72 aremoved inwardly and outwardly, is a latch 148. This latch is in the formof a rectangular metal block or lug formed on the upper side of thebearing blocks 127 and 135. 'When these bearing blocks move upwardly andthe carriages 71 148 in the slots 149 positively prevents inward oroutward movement of the carriages and firmly holds the upper formingrolls car- Red by the carriages in their operative posi- ,gtions.

The dm'ving mechanism diameters and is preferably constructed asfollows: 1

The numeral 150; represents an electric motor which issuitably mountedat one side.

of the bed or frame 23 of the machine and carries a driving pinion 151which drives a gear wheel 152. This gear wheel 152 is keyed to ashaft153 which is suitably journ-aled in the machine frame and has keyedthereto a pinion 154. This pinion 154, as best shown in Fig. 14, mesheswith a gear 155 which gear 155 is fast to a shaft 156. This shaft isjournaled in bearings carried by the fixed and movable pedestals 63 and65 and extends across ithe machine, the opposite endsof this shaftcarrying elongated pinions 157, as best shown in Fig. 9. Eachcarriage 71and 72 carries three idlers 158, the idlers on the carriage 71connecting the elongated pinion 157 and the pinions 103 and 111, whichlast named pinions arerespe'ctivelymounted on the -upper beading rollshaft 101 and the upper fianging roll shaft 109 of the carriage 71 androtate thebeading and flanging rolls. In a I shaft 1010f this carriage,and with the upper fla'nging roll shaft 109, thereby rotating the t theelongated plmons 157 with the gear 132 desired i g of the main (hiveshaft.

similar manner, the idlers 158 on the carriage 72 connect the elongateddriving pinion 15 with the pinion 103 onjhe upper beading ro heading andfiangin grolls-carried by this car'- riage 72. It will be observed thatby reason of the elongation of the pinions-157, 157, when thecarriages71 and 72 are reciprocated toward and from oneanother, the idlers-158are always in engagement therewith andv hence the b'e'adin and flangingrolls are continuously rotated:

Apair of idlers 159 also meshes with the elongated pinions 157 at eachside of the ma: chine, one of these idlers connecting one of mounted-onthe end of the lower. vertically movablefianging rolls shaft 126, andthe th'e'lower forming rolls shafts 126 and 133 to-their'operative' andinoperative positions is relatively slight and doesnot disturb theconnection'of the driving gears carried thereotheridler 159 connectingthis elongated pinion 157 with the gear 160 moun'tedon the end of thelowervertically movable beading rolls shaft 133. The vertical movementof by with the motor.

The power for driving the main shaft 42 which a'ct'uates the cams whichmove]: the carriages back and forth and also the;

lower formingirollsiup and-down and also the Geneva ear drive for theconveyer is arranged as ollows:

Also meshing with the driving pinion 154 1s a carrying a pinion 163.This pinion 163 meshes wlth a gear 164 which is mounted gear 161 whichis fast to a shaft 162 on a shaft 165. On the outer end of the shaft 165is keyed a small pinion 166 which meshes with a large gear 167, keyed tothe outer end of themain drive shaft 42. It is therefore 'ap arentthatthemain drive shaft is in direct an continuous connection with themotor 150 'througha train of gears, and-hence is conpositions, it isapparent that by varying the speed of the driving shaft 42 that themachine can be varied to operate properly on different sizes of barrelshells, it being undesirable to rotate the barrel shells by the formingrolls more than one'complete revolution of the "barrel shell.

For example, with the barrels as shown the rotation of the heading andfia-nging rolls turns the barrels one complete revolution and thebea'ding'and flanging rolls are then withdrawn and the conveyeradvanced. ,If a barrel shell twice the circum ference were being beadedor flanged, the

heading or flanging rolls would bead or flange half the barrel shell andthen the bead ng and fla-nging rolls withdrawn and the barrel advanced.It is obvious that to remedy this defect it is necessary toslow up thespeed or timing of the main drive shaft sons to permit of the largerbarrel shell being completely beaded or flanged before the form ngdevices are withdrawn. This can be accomplished by replacing the gear167 on the driveshaft 42 and its driving pinion 166 by}? gear and pinionhaving the proper ratio to effect the Operation 1 r The operation of theb'eadingand flanging the conveyer arms or flights 35? on 'the upper :orfeedingstretch of the conveyer. f

onthe wheel 30, as shown in Fig.1. The bar'- ,relshells are so fed in a,continuous stream, a barrel. shellbeing arranged between each of i Themotor 150, having been energized thereupon drives the main shaft 42through c the train of gears comprising the pinion 151 on the motorshaft, gear 152, pinion 154, gear 161, pinion 163, gear 164 andinterchangeable pinion and gear 166 and 167. The main drive shaft 42drives the Geneva gear 38 at the opposite side of the machine, the maindrive shaft 42 turning the driving arm 43 four times to every revolutionof the driven or star wheel 39 of the Geneva gear. The star wheel 39 ofthe Geneva gear is carried by the conveyer drive shaft 34 on which thedriving wheels 32 of the two conveyer chains 29 which carry the barrelshells along their upper stretches by means of the "wings or flights 35.This Geneva gear drives the conveyer chains 29 with a step-by-stepmotion, the steps being such as to bring each barrel shell to rest firstat the stationA and then at the station B. While the machine is inoperation, the motor 150 also rotates the upper forming rolls comprisingthe upper beading rolls 100 and the upper flanging rolls 108' carried bythe carriages 71 and 72, and also the lower beading rolls 106 and thelower flanging rolls 113 cooperating with the upper rolls. The upperbeading and flanging rolls-are driven through a train of gearscomprising the pinion 151 on i 30 the motor shaft, gear 152, pinion 154,gear 155, elongated pinions 157, 157 mounted at opposite ends of theshaft 156, the two trains of idlers 158 at opposite sides of the machineon the carriages 71 and 72, and the two pairs :5 of pinions 103 and 111which are respectively secured to the upper beading roll shafts 101 andthe upper flanging roll shafts 109, the beading rolls 100 and theflanging rolls 108 being mounted at the inner ends of these 4 shafts.The lower beading and flanging rolls i106 'and 113 are also continuouslydriven through a train of gearscomprising the pinion.151 on the motorshaft, gear 152, pinion 154, gear 155, elongated pinion 157, pair of,

4.5 idlers 159, and pinions 160 and 132 mounted on the ends of the lowerbeading rolls shaft 133 and lower flanging rolls shaft 126 whichcarrythe lower beading rolls 106 and the lower. flanging rolls 113,respectively. The

upper and lower forming rolls arerotated in opposite directions at thesame speed so that when the opposite ends of the barrels are disposedbetween either the beadingjifir flanging rolls, the same is rotated andlpeaded and flanged.

' In order to center the barrel shells 20 on the colivgeyer and alsomove the upper beading and ii'ahging rolls 100 and 10 8 to their opera-'tive positions, the carriages 71 and 72 which carry the centeringplates are moved together in the following manner:

Thecam wheel on the main drive shaft 42 rocks the arm 88 transversely ofthe machine, this movement of the rock arm rock?- 65 ing the ,rock shaft89, rock arm 90, link arm 92 reciprocates the carriage 71 through thedirect connection of the adjustable rod 95, and at the same time movesthe carriage 72 in the opposite direction through the rod 96, rock beam99 and link 991 which linkis directly connected with the carriage 72. Bymeans of the rock beam 99 the carriage 72 is moved in the oppositedirection to the carriage 71, i. e., the carriages are moved toward andfrom one anot ,r'.

After thecarriages 71 and 72 carrying the upper forming rolls have beenmoved together, the lower forming rolls are moved up into operativerelation to the upper, forming rolls in the following manner:

The cam 115 on the main drive shaft 42 rocks the cradle 118'longitudinally of the machine, this movement, through the links 123 and142 rocking the rockarms 141 and 124 and the rock shafts 140 and 125.The rocking movement of the rock shaft 140 rocks the arms 139 carriedthereby and raises and lowers the links 138 which connect these lastnamed rock arms with the bearing blocks 135 i and rock arm 92. Themovement of the rock supportingthe lower beading rolls shaft 133 andthereby moves the lower beading rolls 106 into and out of operativerelation with the upper beading rolls 100 In a similar manher, therocking of the rock shaft 125 moves the lower flanging rolls 113 intoand out of operative relation with the upper flanging -rolls 108 throughthe rock arms. 26 on the rock shaft 125, and the links 130 which connectthese rock arms with the vertically movable bearing blocks 127 whichcarry thelower flanging rolls shaft 126.

As the lower bearing blocks 127 and 135 are moved upwardly by the cam115 as just described, the locking'lugs 148 carried thereby enter theopenings 149 in the carriages 71 and 72 which have been moved inwardlyand positivly hold these carriages a'gainst either inward and outwardmovement, thereby insuring the maintenance of the positionof the upperforming rolls to properly bead and flange the barrel shells.

The movement of this mechanism is so syn chronized that the Geneva gear38 first advances the conveyer, the cam 85 then moves the carriages 71and 72 together to center thebarrel shells so on the conveyer and alsobring the upper beading rolls 100 and the upper flanging rolls 108 totheir operative positions, the cam 115 then moves the lower beadingrolls 106 and lower flanging rolls 113 into operative relation to theupper beading and flanging rolls, respectively, the cam 115 then lowersthe lower be'ading'rolls 106 and the lower flangingrolls to theirinoperative positions, the cam 85 then withdraws the carriages 71 and 72outwardly and the Geneva gear 38 advances the conveyer another step. By

this means the barrel shells 20 are successive- 1y beaded and flanged asthey are carried along by the conveyer.

The machine is adjustable to diiferent sizes of barrel shells by meansof the various adjustments described, and the synchronization of theforming rolls to the advancing and controlling mechanism is varied bythe simple substitution of gears of the ratio to produce the desiredresult for the gear 167 and pinion 166. v

The barrels are also held in proper relation to'both the beading andflanging rolls by the adjustable rollers 144 and 145 which engage boththe inside and the outside of each end of each barrel being beaded orflanged and also serve to round up the barrel shell as it is turned andinsure a perfectly round headed and flanged product.

As a whole this invention provides a barrel beading and fianging machinewhich is comparatively simple considering the function which itperforms, it operates reliably and efliciently to properly bead andflange barrel shells fed in a'continuous stream, it requires noattention beyond the feeding and removing of the barrel blanks, it willproperly bead and flange barrel shells regardless of substantialvariations in the same, it is easily adjustable to vdifi'erent: sizes ofbarrels and is not liable to get out of order under constant use. p
